Full Feature Video: https://youtu.be/C10XgojHu44 Also full credit to MIT and their fellow grad students for the basic design. I just used this for an educational video and to satisfy my curiosity, this prop was still heavily modified and different to accommodate the drone. These results are not entirely indicative of MITs real props.
OK, sounds like a giant hornet, but I am glad this research is being done. What about testing for wind turbines?
If they put an additional loop in there & rounded out the outer circumference, the drones propellors would be bump resistant.
"The Leaftblower Prop"!
Sounds like honey bees
Yeah im pretty sure that the thing that makes the sound is the enginws ☠️
bruh u talk too much
Toroidal propellers: torrential storm
Rough edges and rough surface is what makes the noise ..
Well, it flies, but it doesn't sound much quieter.
Cant lift to much
Everyone in the comments was expecting a stealth drone .
In a room with dry ice.
Can they make you a better mic?
And? What's the conclusion?
awesome
Did it ever occur to you that the nail polish coating was not smooth enough, resulting in turbulence? In that case it would’ve increased turbulence, reduced efficiency and increased the amount of noise. Production seems flawed.
Not quieter, but I like the sound more than the normal propeller.
Dude can't speak properly
Lol is it just me or do they sound significantly LOUDER than the conventional ones!!!
В самолётики не наигрался? Мы вам устроим…
DIY propeller meets DEI propeller.
Sounds like a “slightly” less angry swam of bees. 😂
I don’t think they’re that different at all – just a different pitch.
SO THEY ARE SUPPOSED TO BE 20% LOUDER
bro, acetone wash or resin print those.
The 3d printed propellers weren't smooth which makes the entire test pointless. The roughness of the surface introduces turbulence which both reduces thrust at a given rpm and increases noise
Not the bees!
Total garbage
You could say it's less irritating but quieter…no
I can’t tell if it’s quieter or louder, the reason I say this is because, if you hear a gunshot on camera with the regular gunshot then with a silencer it sounds like it’s the exact same decibel but just a different sound. I think it’s because the camera can’t actually register something that’s a super high or low decibel but rather just recognizes the noise it makes, so maybe even though the propeller sounds louder on camera, it’s just a different sound that makes it seem loud but in reality is a lot lower of a decibel.
Your 3D print post-processing is ultra cringe
Yeh kya khudko hee opposed karta hain???
"The design is very human"
ithas a lower pitch …. which actually makes it louder lol
My anti-gravity drone doesn't make a sound.
Puff guard needed
Thats how my cfly faith mini sounds but mine is quiter ngl
Sounds like thousands of bees surrounding me
Il est possible que la matiere qui ne serait pas assez épaisse soit déformée par l'inertie de rotation..
You're telling me they are supposed to be quiter and, the moment it's on, it sounds like 10 Lexus LFAs going at the same time!
MIT thinks bees dont make a noise
Actually it is much less sharp of a noise, I'd imagine it being heard from far closer. Aside from the obvious manufacturing issues, this is actually promising.
I'm in a public place, the amount of heads that turned towards me when they heard this primordial roar would constitute grounds for an emotional distress lawsuit
Why'd you add the sound of a skill saw to the start-up of the drones?
Sounds much worse than original. I would assume that more noise means more turbulance, drag.
It has been known for a long time that women apply nail polish to make their nails more aerodynamic
Oh yeah.. quieter…
Wondering what it would sound like with precision machining.
